Introduction
Building roofs are effected by all types of weather and changes in the atmosphere.
Roof expansion and contraction are caused by both freezing and thawing of standing
water in and on roof areas. Thorough and effective roof drainage systems can
eliminate damage to both the roof and substructure of a building.
Watts has an extensive line of roof drains and accessories engineered and designed to
meet the needs and concerns of our customers.
Watts RD-700/RD-800 does the work of two drains in one. These roof drains combine
both a primary and an overflow roof drain saving the contractor labor and time during
installation.
